Looking inside the heart of a supernova from underground
Core-collapse supernovae host some of the most extreme physical environments in our universe. They play a fundamental role in shaping the world around us, from seeding new star formation to spreading heavy elements around the Galaxy. The extreme physical conditions make them very valuable laboratories for particle physics, nuclear physics and astrophysics. In this talk, I will review the basic mechanism driving these gravity-powered neutrino bombs and then discuss examples of the rich physics that is imprinted on the expected neutrino signal. The DUNE experiment currently under development in the US will provide unique capabilities for observing physical processes in and around the collapsed core.
Alex Friedland studied physics first at the Moscow Institute of Physics and Technology and later as a graduate student at the University of California, Berkeley. He became fascinated with neutrinos from supernova explosions while a postdoctoral researcher at the Institute for Advanced Study in Princeton, NJ. He continued exploring the rich physics of supernova neutrinos at Los Alamos National Laboratory, first as a Richard P. Feynman Fellow and then as a permanent staff scientist. In 2015 Friedland became a senior staff scientist at SLAC, where he explores neutrinos in the lab, in stars and in the early universe and pursues broader questions in particle physics and astrophysics.
